Are all the D2 helmet shells the same size but use different size liners to get different fits?
Or are the shells all different sizes and will only fit the coresponding liner?

Troy Lee says
*Interiors cannot be interchanged, since they already combine sizes.

It also looks like Mr Lee is saying that the m/l and the xl/xxl shell are the same size.

Which is why i was asking.

Doesn’t matter now as i’ve ordered both and will keep the one that fits the best.
